Difference between Li-ion and Li-sub batteries
Advantages of Li-ion capacity type batteries Nominal voltage 3.6V and operating voltage remains remarkably smooth throughout its service life Can be used in temperatures between -60°C to +85°C. Lithium sub batteries have the highest energy density of all primary batteries: 650Wh/Kg and 1280Wh/dm3. They have exceptionally low self-discharge characteristics, with an annual self-discharge rate of ≤2%, and are manufactured using a stainless steel case with a metal-glass sealed hermetic welding structure, so the battery's shelf life has been proven to be over 10 years at room temperature. Lithium sub batteries are fully sealed batteries. The battery cover is welded to the battery shell, and the positive and negative terminals are insulated and sealed by a glass-to-metal seal, and the liquid injection hole is also fully sealed by steel ball welding. It does not contain mercury, cadmium, lead and other heavy metals and is not environmentally hazardous.
Lithium sub-batteries are disposable batteries and are not rechargeable. Lithium-ion batteries are rechargeable batteries and can be recharged repeatedly. Lithium sub-batteries and lithium manganese batteries are both disposable lithium ion batteries, i.e. the battery itself cannot be recharged after its capacity is depleted. Lithium sub-battery is called lithium thionyl chloride battery, Li-Socl2, the positive terminal is thionyl chloride, the open circuit voltage is 3.6V, the termination voltage is at 2.0V.
Due to its special chemical characteristics and passivation effect, the annual self-discharge current is less than 1% and the storage life is more than 10 years, so it is widely used as a power source in water meters, electric meters and gas meters.
Lithium-ion batteries are a class of batteries made of lithium metal or lithium alloy as the negative electrode material and using non-aqueous electrolyte solution. Lithium-ion batteries are disposable batteries and lithium-ion batteries are rechargeable cycle batteries. Lithium-ion batteries generally refer to primary lithium-ion batteries, important lithium-manganese, lithium-iron batteries and so on.
Lithium-ion batteries with its high specific energy, long cycle life, a wide range of operating temperatures and other characteristics have attracted great interest and attention, particularly attractive is that the average price per cycle battery is not high, and, also on a downward trend.
